Abstract
A system and method is disclosed for securely binding an arbitrary program to an authorized instance of a generic execution platform. Once the binding process occurs, the protected software application will not exhibit correct behavior unless run on the execution platform to which it is bound. The system and method withstands repeated attacks which tamper with the software application and the execution platform. The system and method present a mechanism to bind a program, P, to any un-trusted execution platform, E, which contains a Trusted Signing Authority (TSA). The TSA may take many alternate forms including a trusted platform module, secure processor, kernel driver, and hardened software agents.
